Description

Technical Field

[0001] This utility model relates to the field of waste cable processing technology, and in particular to an automatic stripping fixture for waste cables. Background Technology

[0002] Waste cables refer to wires and cables that have lost their original use value due to aging, damage, technological obsolescence, or project surplus, but whose core components (such as metal conductors and insulation materials) still have recycling value.

[0003] Patent publication number CN220190330U discloses an automatic stripping fixture for waste cables, including a stripping machine body. A scraping structure for cleaning and guiding the wires is provided on the side of the stripping machine body. The scraping structure includes a sleeve, a deformation part, a connecting ring, and a contact part. The contact part forms a spiral cleaning structure on the inner wall of the sleeve. Although the above patent cleans impurities from the surface of the cable by scraping the insulation layer with the rotating contact part, preventing impurities from entering the stripping machine body and damaging the stripping components, the fixed size of the lead hole during use makes it unsuitable for cables of different thicknesses, thus reducing the efficiency of the fixture.

[0004] Therefore, there is a need for an automatic stripping fixture for discarded cables that can adapt to cables of different thicknesses. Utility Model Content

[0005] In order to overcome the shortcomings of the current patent, which is unable to adapt to cables of different thicknesses due to the fixed size of the lead hole, thus reducing the efficiency of the tooling, the purpose of this utility model is to provide an automatic stripping tooling for waste cables that can adapt to cables of different thicknesses.

[0006] The technical solution is as follows: An automatic stripping fixture for waste cables includes a base, a protective cover, and a stripping mechanism. The protective cover is fixedly connected to the top of the base, and the stripping mechanism is installed inside the protective cover. The stripping mechanism is used to strip the insulation of the cable. The fixture also includes a first servo motor, a bidirectional screw, a guide rod, a mounting base, a connecting plate, rollers, and annular blades. The first servo motor is installed on the top of the protective cover. The bidirectional screw is rotatably connected between the base and the protective cover. The output shaft of the first servo motor is connected to the top of the bidirectional screw through a coupling. The guide rod is fixedly connected between the base and the protective cover. Two mounting bases are slidably installed on the guide rod. The right side of the mounting base is threadedly connected to the bidirectional screw. Two connecting plates are fixedly connected to the mounting base. Rollers are rotatably installed on the two connecting plates, and annular blades are installed on the rollers.

[0007] As a further preferred embodiment, the peeling mechanism includes a connecting rod and a peeling knife. The connecting rod is fixedly connected to the top of the protective cover, and the peeling knife is provided at the lower end of the connecting rod.

[0008] As a further preferred embodiment, it also includes electric slide rails, electric sliders, mounting brackets, rotating shafts, conveying rollers, a second servo motor, and gears. Two electric slide rails are provided on the front side of the protective cover. Electric sliders are slidably mounted on the electric slide rails. The two electric sliders are fixedly connected to the mounting bracket. Two rotating shafts are rotatably mounted on the mounting bracket. Conveying rollers are fixedly connected to the rotating shafts. A second servo motor is mounted on the left side of the mounting bracket. The output shaft of the second servo motor is connected to the upper rotating shaft through a coupling. Gears are provided on the right end of both rotating shafts. The two gears mesh. Multiple wire grooves are provided on the conveying roller.

[0009] As a further preferred option, the peeling knife is conical.

[0010] As a further preferred option, the depth of each wire groove is different.

[0011] As a further preferred option, the front side of the peeling knife blade is thinner.

[0012] Compared with the prior art, this utility model provides an automatic stripping fixture for waste cables, which has the following advantages: 1. The output shaft of the first servo motor drives the bidirectional screw to rotate, which drives the two mounting seats to move in opposite directions or back to back along the guide rod, thereby adjusting the distance between the two rollers according to the thickness of the cable to adapt to cables of different thicknesses and improve the efficiency of the fixture.

[0013] 2. The output shaft of the second servo motor rotates, driving the connected shaft to rotate. The two shafts rotate synchronously through gear meshing. The rotation of the shaft drives the conveyor roller to rotate, thereby automatically conveying the cable backward and improving the stripping efficiency.

[0014] 3. The ring blade rotates with the roller to cut into the cable surface at a preset depth. As the cable continues to feed, the stripping blade cuts the insulation layer axially. The two work together to form a composite stripping process, ensuring that the insulation layer is completely stripped and avoiding residue. Attached Figure Description

Detailed Implementation

[0021] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning. Unless otherwise specified, terms such as "connection" and "linkage" in this application include both direct and indirect connections (linkages).

[0022] Example 1: An automatic stripping fixture for discarded cables, please refer to [link / reference]. Figures 1-5The system includes a base 1, a protective cover 2, and a stripping mechanism. The protective cover 2 is fixedly connected to the top of the base 1. The stripping mechanism is installed inside the protective cover 2 and is used to strip the insulation of the cable. The stripping mechanism includes a connecting rod 18 and a stripping knife 19. The connecting rod 18 is fixedly connected to the top of the protective cover 2, and the stripping knife 19 is installed at the lower end of the connecting rod 18. A first servo motor 3 is installed on the top of the protective cover 2. A bidirectional screw 4 is rotatably connected between the base 1 and the protective cover 2. The output shaft of the first servo motor 3 is connected to the top end of the bidirectional screw 4 through a coupling. A guide rod 5 is fixedly connected between the base 1 and the protective cover 2. Two mounting seats 6 are slidably installed on the guide rod 5. The right side of the mounting seat 6 is threaded to the bidirectional screw 4. Two connecting plates 7 are fixedly connected to the mounting seats 6. Rollers 8 are rotatably installed on the two connecting plates 7. The device has a ring-shaped blade 9. Two electric slide rails 10 are provided on the front side of the protective cover 2. Electric sliders 11 are slidably mounted on the electric slide rails 10. The two electric sliders 11 are fixedly connected to the mounting frame 12. Two rotating shafts 13 are rotatably mounted on the mounting frame 12. A conveying roller 14 is fixedly connected to the rotating shaft 13. A second servo motor 15 is mounted on the left side of the mounting frame 12. The output shaft of the second servo motor 15 is connected to the upper rotating shaft 13 through a coupling. Gears 16 are provided on the right end of both rotating shafts 13. The two gears 16 mesh. Several wire grooves 17 are opened on the conveying roller 14. The depth of each wire groove 17 is different, so as to be suitable for cables of different diameters. The stripping knife 19 is conical. The conical knife can optimize the angle and reduce the pulling resistance. The front side of the stripping knife 19 blade is thinner, which makes it easier to cut into the insulation layer of the cable and ensure that the insulation layer is completely stripped.

[0023] When stripping waste cables is required, firstly, the first servo motor 3 is started. The output shaft of the first servo motor 3 rotates, driving the bidirectional screw 4 to rotate, which in turn moves the two mounting seats 6 along the guide rod 5 in opposite directions or back to back. This adjusts the distance between the two rollers 8 according to the cable thickness, accommodating cables of different thicknesses and improving the efficiency of the tooling. After adjustment, the first servo motor 3 is turned off. Then, the cable is placed into the matching wire groove 17 according to its diameter. After placement, the electric slide rail 10 is started, controlling the electric slider 11 to move laterally, driving the mounting bracket 12 to shift as a whole, adjusting the position of the cable so that it is positioned between the two rollers 8. Finally, the cable is threaded through the two rollers 8. Between the rollers 8, the annular blade 9 contacts the cable surface and continues to pull the cable through the stripping blade 19, completing the cable placement. Subsequently, the second servo motor 15 is started. The output shaft of the second servo motor 15 rotates, driving the connected rotating shaft 13 to rotate. Through the meshing of the gear 16, the two rotating shafts 13 rotate synchronously. The rotation of the rotating shaft 13 drives the conveying roller 14 to rotate, thereby automatically conveying the cable backward, improving the stripping efficiency. During the conveying process, the annular blade 9 rotates with the rollers 8, cutting into the cable surface at a preset depth. As the cable continues to feed, the stripping blade 19 cuts open the insulation layer axially. The two work together to form a composite stripping, ensuring that the insulation layer is completely stripped and avoiding residue.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
